I bought this oven on 6/7/13. The top open works great, love the convection features and steady heat. The bottom oven has given me nothing but trouble. I lost an entire pork shoulder that I tried to cook overnight and the oven never heated. Now it's the day before my family's Thanksgiving and the bottom oven is again not heating up. We've reset the breaker multiple times and nothing. The repairman warned me that it wouldn't be a cheap fix. Great. Next time I'm going to skip the Bosch oven and go with a different manufacturer.
